Embodiment 2, referring to shown in Fig. 2 to Fig. 3, electric car automatic fire extinguisher provided by the embodiment of the present invention,
The technical effect and embodiment 1 of realization principle and generation is identical, and to briefly describe, the present embodiment does not refer to place, can refer to reality
Apply corresponding contents in example 1.
The electric car automatic fire extinguisher 100 obtained by above-mentioned design has been able to satisfy the use of self-extinguishing substantially,
But in line with the objective for further improving its function, designer has carried out further improvement to the device.
Specifically, in the present embodiment, the control circuit board 112 welds socket 40 and the controller LAN by plate
Network bus 12 connects, and the plate weldering socket 40 includes at least two power pins, two CAN bus pins, four
The automatically controlled fire extinguisher pin of root, wherein power pins are for connecting 24V power supply, and CAN bus pin is for connecting control
Device Area Network bus 12 processed, automatically controlled fire extinguisher pin is for connecting automatically controlled fire extinguisher 30.
Specifically, it is equipped with temperature sensing cable in the automatically controlled fire extinguisher 30 each in the present embodiment, specifically, automatically controlled
After fire extinguisher 30 erupts, the temperature-sensitive circuit inside automatically controlled fire extinguisher 30 is short-circuit, by the way that electricity is arranged in the port of automatically controlled fire extinguisher 30
Sensor is hindered, after resistance value becomes zero between two feedback feet that electric resistance sensor detects automatically controlled fire extinguisher 30, to control
Circuit board 112 sends a status information, and shows on display 11, such as: " * * fire extinguishing ".
Specifically, in the present embodiment, the control circuit board 112 is also connect with a toggle switch 50, specifically, this
Device can access 64 tunnel detection components more, and the number of detection components 20 is (0~63), sets corresponding volume by toggle switch 50
Number definition, dial-up number calculation method is as follows: toggle switch is defined as A, B, C, D, E, F from left to right, respectively correspond digital 1~
6, be in it is digital when being 0, push when relative position it is corresponding it is digital be 1;Then encoded by following formula:
ID=A*20+B*21+C*22+D*23+E*24+F*25
Coding of displays explanation: the present apparatus can at most connect 64 detection components 20, but specifically connection quantity needs to determine
Justice.Method are as follows: resistance R11, R13, R15, R19, R20, R21 do not weld expression 1, and 0 Europe resistance of welding indicates 0.Corresponding weight
Successively are as follows: 1,2,4,8,16,32.Such as: sample will connect 6 detection components 20:6=2+4, and then only R13 and R15 are not welded
It connects, remaining 0 Europe resistance of welding.
Specifically, in embodiment, the side of the display screen 113 is equipped with a buzzer 60, the buzzer 60 with
The control circuit board 112 is electrically connected.The side of the display screen 113 is additionally provided with three state display lamps 70, each described
State display lamp 70 is electrically connected with the control circuit board 112, and the display color of three state display lamps 70 is different, together
When, the control circuit board 112 is also connect with a reset switch 80, and the reset switch 80 is set to the table of the shell 111
Face;The electronic fire extinguisher 30 is also connect with a manual switch 90.
By said structure design, different fire alarm grade differences may be implemented and show.Specifically, the reply of fire alarm grade is arranged
Apply: level-one fire alarm-display screen 113 shows " * * fire alarm ", and state display lamp 70 only has the blinking red lamp, " drop-drop-of buzzer 60
Drop ... " alarm.Automatically controlled fire extinguisher 30 does not spray automatically.Multiple alarm-display screen 113 shows " * * fire alarm ", state display lamp
70 only red wait flash, buzzer 60 " drop-drop-drop ... " alarm.Electronic fire extinguisher 30 does not spray automatically.Three-level fire alarm-display
113 display " * * fire alarm " of screen, state display lamp 70 only have red equal flashing, buzzer 60 " drop-drop-drop ... " alarm.It is electronic
Fire extinguisher 30 sprays automatically.Referring specifically to following table:
Specifically, the sensor coding in detection components 20 are as follows:
ID:0x200+ sensor number
Data0: alarm code (is seen the above table)
Data1: upper nibble position driving executes label, and executing is 1, and not executing is 0, and lower nibble is that fire extinguishing returns to mark
Note, is successfully 1, unsuccessful is 0.
Data2: working state of system: being 1 in starting, working normally is 0.
Data3~7: retain, be 0.
The coding of display 11 are as follows: ID:0x110
Fire extinguisher body.Extinguishing chemical in fire extinguisher is aerosol, and injection triggering mode is automatically controlled mode.Fire extinguisher itself
There are four outlets, two of them are the power supply lines electrically activated, electrically activate trigger condition: DC24V 350mA.Two other line is
Signal feedback line, under non-eruptivity, the resistance value between this two lines is considered as infinity.After starting eruption, two feedbacks
Line connection, being considered as resistance is 0.Therefore, judge this resistance is widely varied the foundation that can be used as fire extinguisher start completion.
Use about manual switch 90: in manual switch 90, continue to send to CAN bus after pressing
CAN (controller local area network's agreement) signal 10min is sent frequency 1-3s/ times.It is all to have in detection components 20 in this 10min
Sensor detect fire behavior, fire extinguishing starting is carried out to the automatically controlled fire extinguisher 30 of oneself control.And by after fire extinguishing " * * goes out
Fire " information feedback display screen 113 is shown.If do not alarmed, even if manual switch 90 is pressed, also without any movement.
" * * fire extinguishing " display information is override, when feedback information of putting out a fire occurs simultaneously with warning message, is only shown
" * * fire extinguishing ", scrolling display, every page at most shows two contents numbered, 1 second/page." * * fire alarm " alarm stops aobvious
Show, but the alarm of the blinking red lamp of buzzer 60 " tick-ticking-tick ... " and state display lamp 90 is normal to be executed.
About reset switch 80, it is mainly used for crashing or the manual of other abnormal failures is restarted.Concrete operations are as follows: press multiple
Bit switch power-off after 80s, release re-powers and self-test.Note: this operation is considered as warm boot, and it is pre- not need preposition 2min
Heat.
Under normal operating conditions, display screen 113 shows " normal work ", and buzzer 60 does not pipe, state display lamp 70
There is green length bright;When communication failure, screen is shown " * * failure ", buzzer 60 " drop-drop-drop ... " alarm, state display lamp
Only blinking yellow illumination.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
